The aryl radical cyclization in solution using N-(2-bromophenyl)- N-methyl-3-phenylacrylamide
Solid-phase synthesis of indol-2-ones by microwave-assisted radical cyclization
Scheme 2
By contrast, the aryl radical cyclization in solution using N-(2-bromophenyl)- N-methyl-3-phenylacrylamide (9) under microwave irradiation (toluene, 50 W, 40 min) scarcely proceeded (Scheme 2).
